Choosing Rootstock and Scion Wood

Selecting the appropriate rootstock and scion wood is crucial for successful persimmon tree grafting. The rootstock provides the root system and influences the growth vigor, disease resistance, and adaptability to soil conditions. The scion is the desired persimmon variety that will produce the fruit.

For persimmons, common rootstocks include:

  • Diospyros virginiana (American persimmon): offers good disease resistance and is well-suited for North American climates.
  • Diospyros lotus (date-plum): often used in warmer climates with tolerance to different soil types.
  • Seedlings of the same species as the scion can also serve as rootstocks, especially for Asian persimmons (Diospyros kaki).

When selecting scion wood, choose healthy, disease-free branches from the previous season’s growth. The wood should be mature but not overly woody, typically pencil-thick, with several buds visible.

Key considerations for scion wood:

  • Collect during dormancy, usually late winter to early spring before bud break.
  • Store in a cool, moist environment if not grafting immediately.
  • Ensure compatibility with the chosen rootstock species to increase graft success.

Preparation of Rootstock and Scion

Proper preparation of both rootstock and scion wood enhances the chances of a successful graft union.

Rootstock Preparation:

  • Cut the rootstock to a suitable height, generally 6 to 12 inches above the ground, depending on the desired final tree height.
  • Make smooth, clean cuts to avoid tissue damage.
  • Remove any competing shoots or buds from the rootstock that could divert energy from the graft.

Scion Preparation:

  • Select healthy shoots containing 2 to 3 buds.
  • Trim the base of the scion to create a fresh, angled cut that will maximize cambium contact with the rootstock.
  • Avoid drying out the scion by wrapping it in moist paper or placing it in a plastic bag until grafting.

Common Grafting Techniques for Persimmon Trees

Several grafting methods are effective for persimmons. The choice depends on the season, rootstock size, and scion material available.

  • Whip and Tongue Graft: Preferred for scions and rootstocks of similar diameter. It provides a strong union with good cambial contact.
  • Cleft Graft: Used when the rootstock is larger in diameter than the scion. The rootstock is split, and the scion is inserted into the cleft.
  • Bark Graft: Suitable for larger rootstocks with mature bark. The scion is inserted between the bark and wood of the rootstock.
  • Approach Graft: Both rootstock and scion remain attached to their original roots until the graft union forms, after which one is severed.

Each method requires careful alignment of the cambium layers—the thin green layer just beneath the bark—to ensure proper nutrient and water flow between rootstock and scion.

Step-by-Step Whip and Tongue Graft Process

  • Select matching diameter rootstock and scion (approximately pencil thickness).
  • Make a slanting cut about 1.5 to 2 inches long on both rootstock and scion.
  • Create a tongue by making a vertical slit about half the length of the slant cut on both pieces. The tongues should interlock.
  • Fit the rootstock and scion together by sliding the tongues into one another.
  • Wrap the graft union tightly with grafting tape or parafilm to prevent moisture loss and infection.
  • Seal the union with grafting wax or a similar protective coating.
  • Label the graft for future identification.

Aftercare and Monitoring of Grafted Persimmons

After successful grafting, diligent care is essential to encourage union formation and healthy growth.

  • Keep the grafted area shaded and protected from direct sunlight for the first few weeks.
  • Maintain consistent moisture in the soil but avoid waterlogging.
  • Remove any shoots emerging from the rootstock below the graft to prevent competition.
  • Inspect the graft regularly for signs of union, such as swelling and bud break on the scion.
  • Gradually acclimate the grafted tree to full sunlight as it strengthens.
Care Aspect Recommended Action Timeframe
Graft Protection Wrap with grafting tape and apply wax Immediately after grafting
Moisture Management Water regularly, avoid waterlogging Throughout growing season
Sunlight Exposure Shade graft site initially, then increase exposure First 2-4 weeks post-grafting
Rootstock Shoot Removal Prune any shoots below graft union As soon as shoots appear
Scion Growth Monitoring Check for bud break and healthy growth 2-6 weeks post-grafting

Selecting Rootstock and Scion Wood

Successful persimmon grafting begins with choosing compatible rootstock and scion wood. The rootstock serves as the base and provides the root system, while the scion is the desired cultivar that will grow into the new tree canopy.

Rootstock Selection:

  • Species Compatibility: Use Diospyros kaki rootstock for Asian persimmons or Diospyros virginiana for American persimmons; interspecific hybrids require compatible rootstock.
  • Health and Vigor: Select disease-free, vigorous rootstock approximately 1 to 2 years old with a diameter of ¼ to ½ inch.
  • Climate Adaptation: Choose rootstock adapted to local soil and climate conditions to ensure strong establishment and growth.

Scion Wood Selection:

  • Timing: Collect dormant scion wood during late winter or early spring before bud break.
  • Wood Quality: Select healthy, one-year-old shoots with well-developed buds.
  • Length and Diameter: Cut scion pieces 4 to 6 inches long with a diameter matching the rootstock for optimal graft union.

Preparing the Rootstock and Scion

Proper preparation of both rootstock and scion is critical to ensure a successful graft union.

Rootstock Preparation:

  • Trim the rootstock at the desired grafting height using a sharp, sterilized pruning tool.
  • Remove any lateral branches or leaves near the graft site to reduce moisture loss and facilitate handling.
  • Make a clean cut to expose fresh cambium tissue, which is essential for graft union formation.

Scion Preparation:

  • Trim the base of the scion wood into the required shape depending on the grafting method (e.g., wedge, whip, or cleft).
  • Ensure the cut surfaces are smooth and freshly made to maximize cambium contact.
  • Keep scion wood moist and shaded until grafting to prevent desiccation.

Common Grafting Techniques for Persimmon Trees

Several grafting methods are effective for persimmons. The choice depends on the size of the rootstock and scion, as well as grower preference.

Grafting Method Description Best Used When Advantages
Whip and Tongue Graft Both rootstock and scion are cut with matching slanting cuts and a tongue to interlock them. When rootstock and scion diameters are similar and small (1/4 to 1/2 inch). Strong mechanical union, good cambium contact, high success rate.
Cleft Graft Rootstock is split vertically, and wedge-shaped scion is inserted into the cleft. When rootstock is larger in diameter than scion. Allows grafting of multiple scions on one rootstock, relatively simple.
Approach Graft Both rootstock and scion remain attached to their original plants and are joined together. When both plants are mature and close together. High success, no need to sever scion from parent until union is strong.

Executing the Graft Union

Precision during the grafting process is essential to establish a successful union between scion and rootstock.

Steps to Perform the Graft:

  1. Align the cambium layers of the scion and rootstock carefully; the cambium is the thin greenish layer just beneath the bark.
  2. Fit the scion and rootstock together tightly without gaps to maximize contact.
  3. Secure the graft union firmly with grafting tape, rubber bands, or parafilm to hold the pieces in place and prevent drying.
  4. Apply grafting wax or sealant over the exposed cuts to reduce moisture loss and prevent infection.

Post-Grafting Care:

  • Keep grafted plants in a shaded, humid environment to reduce desiccation stress.
  • Water the rootstock regularly but avoid waterlogging.
  • Inspect the graft union weekly for signs of growth or infection.
  • Remove any shoots emerging below the graft to direct energy to the scion.

Timing and Environmental Considerations

The timing of grafting and environmental conditions significantly influence the success rate.

Optimal Timing:

  • Perform grafting in late winter to early spring, just before the sap flow begins and buds start swelling.
  • Avoid grafting during extreme cold, frost, or drought conditions to minimize stress on the plant.
